i#3674: Add stack alignment to test that is calling "vfprintf". (#3676)

An Ubuntu 18 system's libc, even with older gcc versions 4.8 (we did not try
< 4.5), decided to callee-save a xmm register on the stack. This patch aligns
the stack in the function in the test that is calling vfprintf. This problem generally
affects all functions that we are hand-coding in asm and calling from a test.
Absent a complete review of all hand-coded functions in the code base, this
fixes this one only single case where a test failure was observed.

Fixes #3674

About DynamoRIO

DynamoRIO is a runtime code manipulation system that supports code transformations on any part of a program, while it executes. DynamoRIO exports an interface for building dynamic tools for a wide variety of uses: program analysis and understanding, profiling, instrumentation, optimization, translation, etc. Unlike many dynamic tool systems, DynamoRIO is not limited to insertion of callouts/trampolines and allows arbitrary modifications to application instructions via a powerful IA-32/AMD64/ARM/AArch64 instruction manipulation library. DynamoRIO provides efficient, transparent, and comprehensive manipulation of unmodified applications running on stock operating systems (Windows, Linux, or Android) and commodity IA-32, AMD64, ARM, and AArch64 hardware. Mac OSX support is in progress.

Existing DynamoRIO-based tools

Tools built on DynamoRIO and provided in our release package include:

  • The memory debugging tool Dr. Memory
  • The multi-process cache simulator and memory address trace collection and analysis platform drcachesim
  • The legacy processor emulator drcpusim
  • The “strace for Windows” tool drstrace
  • The code coverage tool drcov
  • The library tracing tool drltrace
  • The memory tracing tool memtrace
  • The basic block tracing tool bbbuf
  • The instruction counting tool inscount

Building your own custom tools

DynamoRIO‘s powerful API abstracts away the details of the underlying infrastructure and allows the tool builder to concentrate on analyzing or modifying the application’s runtime code stream. API documentation is included in the release package and can also be browsed online. Slides from our past tutorials are also available.

Downloading DynamoRIO

DynamoRIO is available free of charge as a binary package for both Windows and Linux. DynamoRIO's source code is available under a BSD license.
